Excalibot was a superheavyweight robot which competed in Season 4.0 of BattleBots. It was a silver four-wheel box-shaped robot armed with a pneumatic ram and two wedges on the front and rear. It didn't perform well in competition, losing its first match against Marauder.
Its name was a pun on the legendary sword Excalibur.
The match started with Excalibot showing off its ramming force, slamming Marauder and then the wall very hard. The robots then went into pushing and shoving mode and managed to get a few more rams on each other and the hapless walls. Although Marauder's lifter didn't work, it still took control, ramming Excalibot and smacking it up into the spikes, knocking it all around until Excalibot died.
- Wins: 0

Excalibot is one of two one-time loser robots that fought Marauder, the other was Cannibot.
